Using the Magento Order Approval Manager Extension:

Support Non-Paying Customers – If the person who use the product is not the person who pays for it, this extension is the way to provide the ability to support submitting the order without making an actual payment.

Complete the B2B process – B2B process requires a different payment process than a regular B2C store. Each purchase needs to be approved and usually the person who needs the product is not the person who pays for it, this extension fully supports this process

Magento Order Approval Extension Features

Complete Order before paying for it – Orders are saved in pending mode once submitted until paid.

Email notification for the buyer and payer – When an order is created using the order approval payment method, an email notification is sent to the buyer with the order details, and to the payer with information on how to complete or cancel the order. When an order is completed or canceled the buyer is again notified.

Email reminders to the payer – Payers receive email reminders about pending orders waiting for their review and payment.

Link redirecting to Checkout in Payer notification email – When the payer clicks on the email link to complete the order it takes them directly to the payment step for the order. All billing and shipping info is already set (can be edited).

Separate admin section – Admins can manage orders waiting for approval which are in pending mode.
